REFRlG'ERAToRnCAR.

SPECIFICATION formingpart of Letters Patent No. 270,383, dated January 9, 1883. Applicata@ ined september 1s, issn. (No mona.)

To all whom it may concern:

Be it known that. I, BENJAMIN N. BUGBEY, of Sacrainento,in the county of Sacramento and State of California, have invented a new and Improved Refrigerator-Car, of which the followingis a full, clear, and exact desciiption.

My invention consists of a layer of clay, plaster-of-paris, or other porous absorbent material, located between the outer shell of boards and an inner partition, the said clay or plaster layer being' provided with a system ot' water-courses of perforated metallic pipes, clay pipes, or otherwise-formed water channels or courses arranged for the circulation of water throughout the clay or plaster for saturating it to produce a cooling e'ect by evaporation; and the inventioniconsists ofthe combination, with the said evaporating-layer, of an inner course or layer of charcoal, pulverized and closely packed between partitions of the sides of the car, for the destruction ot' unpleasant odors from the goods in transit, and in the coinbination, with said system of water-courses in a clay or plaster layer and the said charcoal layer, of a layer of sawdust to take up the danipness and protect the interior of the. car from moisture, all as hereinafter full)` described.

Reference is to be had to the accompanying' drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in both the figures.

Figure lis a longitudinal sectional elevation of' a refrigeratorca-r constructed according.;` to my invention; and Fig". 2 is a transverse section ofthe car.

Next to the exterior wood case or covering of the car-body a., I propose to apply a clay, pl-.isterof-paris, or other 'porous and absorbent layer or shell, l), about one inch thick. more or less, with a wood partitioiuc, to coniine it inside, in which'- clay or plaster shell I arrange any preferred forni of water-passages d in coils formequal distribution of the water throughout the whole extent of the clay shell for causing` evaporation, and thereby produc ing, the cooling effect thereof as a means of cooling the car for the protection of perishable goods without the use of ice. The water may be poured into the circulating channels or courses through a funnel, e, at'the top of the car. Inside of` partition c, and between it and apartition, g, I apply a layer,f, of charcoal, preferably pulverized ,and snugly packed, of one-half inch (more or less) in thickness,

which serves to destroy any unpleasant odors from outside sources and from the goods in" transit, and thus avoid impregnation ot'fone class of merchandise with the distinctive odors ot' another kind of goods and preserve perishable freight on longjournelvs. To protect the 6o car from moisture that might result trom the use of water in pipes d and the nature of the goods carried, I arrange an inside layer ot'sawdust, Ii, one inch (more or less) in thickness, between partition g and an inner one, t', as 65 shown, and thereby etfectually protect the car, the sawdust taking up the moisture and keeping the interior of the car dry.

I propose to employ any approved system of ventilators It for the circulation of air through- 7o out the car, and to supply the air for the evaporating` process. Iprefer to use redwood foi' the partitionsaiid for the sawdust filling; but other woods will serve well. v

The body will be alike protected on all sides, ends, top, and bottom, or not, as preferred.

' Having thus described my invention, what I claiin as new, and desire to secure by Letters Patent, is-

l. 'Ihe combination, with the shell or body 8o of a refrigerating-oar, of a lining or shell of clay, plaster-otlparis, or other porous material, having` a series of pipes or other passages embedded therein for the distribution of water throughout the lining or shell for cooling the car by evaporation of the water therein, substantially as described.

2. The combination, with the shell or body of a refrigerating-car, of a lining or shell of clay, plaster-of-piris, or other porous material, 9o having a sexies of watercirculating pipes einbedded therein for inoistening the same, and the liiiin,9;layerofcharcoal'to serve asad'eodoriZer, substantially as shown and described.

8. ,The combination, with the shell or body 0f a refrigerator-car, of a lining` or shell of clay, plaster-of-paris, or other porous material, having a series ot' pipes or other passages embedded therein for inoisteningthe same, of the charcoal layerf as a deoilorize'r, and 4ot an inron Iier layer or lliiig of sawdust for absorbing the moisture and protecting the car therefrom, substantially as described.
